Ergocalciferol

And it's called heme iron, okay? Like from steak or liver, things like that.

And then let's get to number seven, vitamin D2, ergocalciferol.

This is not the natural version of vitamin D.

When you take high doses of D2, it gets rid of excess D3.

There's vitamin D3, which is the kind of vitamin D you can get over the counter at the health food store or at the pharmacy without a prescription.

And then there's vitamin D2.

Vitamin D2, you have to have a prescription to get.

And so in many doctors, doctor brain, that means that it must be the right kind if you have to have a prescription to get it.

And that in this case, the doctor brain is absolutely wrong.

Vitamin D3 is much better absorbed than vitamin D2.

It's a much more natural way of taking it and you actually get much more of an absorption rate from taking vitamin D3.

So if your doctor prescribes you vitamin D2, 10,000 units or 50,000 units a week or a month, nod and smile and be respectful and then go buy some vitamin D3 and take that one today because that's a much more natural way to get your vitamin D.

How so?

When you look at the shelf, you primarily have vitamin D2, which is ergocalciferol.

That's derived from plants and fungi.

And then you have vitamin D3, cholecalciferol, which comes from animal sources and is what your skin naturally synthesizes when exposed to UVB sunlight.

Number five.

Vitamin D2, which is mainly you have to get a prescription for, is very different than vitamin D3.

In fact, vitamin D2 actually in some studies have worsened MS, okay, versus vitamin D3 has greatly improved MS. Lupus, another autoimmune disease, uh, is not affected by D2, but it is with D3.

The studies in vitamin D2 do not decrease mortality, but the studies with vitamin D3 do.

And taking vitamin D2 can actually inhibit the absorption of vitamin D3.

All right.

Next point, okay? Um, some people, when they go out and get exposure to the sun, uh, they think that they're getting a lot of vitamin D when they're getting exposed to the sun for like ten minutes.
